Answer:

4 m/s

Explanation:

Step 1: Given data

  • Mass of the balloon (m): 400 kg
  • Kinetic energy of the balloon (KE): 3200 J

Step 2: Calculate the velocity (v) of the balloon

The kinetic energy is the energy that the balloon has due to its movement. We can calculate the velocity of the balloon using the following expression.

v = √(2 × KE/m)

v = √(2 × 3200 J/400 kg) = 4 m/s

Correct answer is <span>X = ΔH

Reason:
1) The graph of enthalpy Vs reaction coordinate  suggest the reaction is endothermic in nature. For endothermic reaction, energy if product is more than that of reactant. Hence,  option 1 i.e. </span><span>X = -ΔH cannot be correct.
2) Since the reaction is endothermic in nature, </span>energy if product is more than that of reactant. Hence,  option 2 i.e. X = ΔH is correct.
3) Activation energy is energy difference between Reactant (A) and transition state (B). However, as per option C, activation energy (A.E.) is energy difference between product (C) and transition state (B), which is incorrect.

True or False: It is OK to use wet glassware for the aspirin synthesis without potentially affecting your yield
vesna_86 [32]

Answer:

False

Explanation:

Laboratory synthesis of aspirin is done by the acetylation of salicylic acid with the help of acetic anhydride .

As , the  acid anhydride is very sensitive to moisture , as it can hydrolyze into two molecules of  acids,

Hence , the reaction involving acid anhydride  are conducted in anhydrous solvents .

Hence ,

if water is  present in the glassware then , some of the acetic anhydride is wasted , Which in turns reduces the yield than that expected .
